Abstract (en)
Apparatus and method of antitachycardia pacing in a dual chamber pacing device including means for or steps of detecting the presence of a tachycardia, measuring the tachycardia cycle length, determining a VA interval value less than or equal to the tachycardia cycle length, determining an initial value of the AV delay interval, delivering pulses to the ventricle and to the atrium until the expiration of N VA intervals and N AV intervals thereby completing a first train of pulses, delivering a series of M trains of pulses similar to said first train of pulses, and varying the AV delay interval value from the initial value at least once prior to the completion of the series of M trains of pulses. Monitoring of instrinsic QRS complexes between pulse trains is performed. If the tachyarrhythmia is deemed to be accelerating, one of cardioversion or defibrillation may be applied. <IMAGE>
